As far as can be ascertained by (admittedly traces of) evidence, ALL of the Apostles went to the Gentiles. Even Peter, the "Apostle to the Jews," and James who was head of the Church in Jerusalem and martyred there, ministered also to Gentiles.
As far as we know (and some of this is based on physical traces --- buildings, graves, steles and other monuments --- which have now long been destroyed, especially in what are now Muslim lands) --- various apostles ministered and died in Spain, in Rome, in Egypt, in Jerusalem, in Scythia and Parthia, in Ethiopia, in Armenia, in western Assyria and the Nineveh plain, and on various Greek islands.
They all ministered both to Gentiles and to Jews in various cities in the Roman Empire and even beyond the borders of the Empire.
I'm not going into a lot of detail, because I don't think we know a lot of detail. I just read ISIS ransacked Mosul Museum and destroyed ancient manuscripts and books in its library, dynamited churches and bulldozed the ancient Assyrian city of Nimrud.
